Infinity has released a belt tensioner flange for use on both their IF18 and IF15 nitro on-road chassis. This tension roller flange prevents the middle belt from accidentally falling off in high load situations such as high temperatures or extreme high traction. Fixed in place so as not to increase rotating mass of the roller, it is also shaped to prevent any step between the belt and the flange. It is available in black or titian colours. An M3x15mm screw is included for when fitting on the IF15.
